Tuning Guidelines

Observe the following guidelines when tuning performance:

• Analyze resource bottlenecks from multiple aspects to identify the root cause. For example, high CPU usage may be caused by limited memory capacity. The CPU resources are exhausted by memory scheduling.
• Adjust only one performance metric parameter at a time.
• The analysis tool may consume system resources and aggravate certain system resource bottlenecks. Therefore, the impact on applications must be avoided or minimized.
